Get protocols » The most complex part of using UCEs to understand evolutionary relationships, population structure, and population relationships is analyzing the DNA sequence data. Mc Cormack JE, Harvey MG, Faircloth BC, Crawford NG, Glenn TC, Brumfield RT. A Phylogeny of Birds Based on Over 1,500 Loci Collected by Target Enrichment and High-Throughput Sequencing. Generally speaking, these commercial vendors will accept DNA extracts for enrichment, conduct the library preparation and enrichment steps, sequence the enriched libraries, and return the sequence data to you. We are constantly evaluating the utility of given probe sets and probe designs, in addition to expanding the number of UCE loci we are targeting.
